I am using OpenCore 0.5.9 on a macOS Catalina hackintosh. As described in the question itself, I can't manage to enable audio output to external devices like my Logitech external speakers or through HDMI to my Samsung TV. My internal audio works fine and so does audio output through BT devices. I just can't seem to enable audio through wired connections such as HDMI or for my Logitech (non-BT) external speakers. I would greatly appreciate any help offered! Thank you.
